Cell communication is the process by which cells send and receive signals to coordinate their activities. This communication is essential for maintaining homeostasis and allowing cells to respond to changes in their environment. Cells use various methods, such as chemical signals, to communicate with each other, ensuring that they work together effectively. There are two main types of cell communication: autocrine and paracrine. In autocrine signaling, a cell releases signals that bind to its own receptors, while in paracrine signaling, signals affect nearby cells. Additionally, hormones can be released into the bloodstream for long-distance communication between cells in different parts of the body.
